## **Applications** - Switching applications ## **Description** This Power MOSFET has been developed using STMicroelectronics’ unique STripFET™ process, which is specifically designed to minimize input capacitance and gate charge. This renders the device suitable for use as primary switch in advanced high-efficiency isolated DC-DC converters for telecom and computer applications, and applications with low gate charge driving requirements. ## **Figure 1.
